Paramagnetic Substance: Attraction to Magnetic Field

  • Thread starter Hardik Batra
  • Start date
In summary, a paramagnetic substance is a material with unpaired electrons that exhibits a weak attraction to a magnetic field. It aligns with the field to create a net attraction, but this is weaker than a ferromagnetic substance. The main difference between paramagnetism and ferromagnetism is the strength of this attraction. Some examples of paramagnetic substances are aluminum, platinum, and oxygen. While it can be temporarily magnetized in the presence of a strong field, a paramagnetic substance cannot become a magnet on its own.

When a para magnetic substance is brought near a north pole or a south pole of a bar magnet it
experiences attraction. How?Hint : when you put the para magnetic substance in external magnetic field it magnetize. So it experiences the resultant force towards the stronger magnetic field.

Paramagnets in external magnetic fields acquire a net average magnetic dipole moment due to the thermal averaging over the unpaired spins of the atoms in the magnet coupled to the external field.
 

What is a paramagnetic substance?

A paramagnetic substance is a material that exhibits a weak attraction to a magnetic field. This attraction is caused by the presence of unpaired electrons in the atoms of the substance.

How does a paramagnetic substance behave in a magnetic field?

In a magnetic field, a paramagnetic substance will align its dipoles with the field, resulting in a net attraction. However, this attraction is relatively weak compared to the attraction of a ferromagnetic substance.

What is the difference between paramagnetism and ferromagnetism?

The main difference between paramagnetism and ferromagnetism is the strength of the attraction to a magnetic field. While both types of substances are attracted to a magnetic field, ferromagnetic materials have a much stronger attraction due to their unique atomic structure.

What are some examples of paramagnetic substances?

Some common examples of paramagnetic substances include aluminum, platinum, and oxygen. These substances have unpaired electrons in their outermost electron shells, causing them to exhibit a weak attraction to a magnetic field.

Can a paramagnetic substance become a magnet?

No, a paramagnetic substance cannot become a magnet on its own. However, it can be temporarily magnetized when in the presence of a strong magnetic field, but this magnetism will disappear when the field is removed.
